It only includes E5 v1 (Sandy Bridge Xeon) device IDs so would need to be updated to include E5 v2 (Ivy Bridge) and v3 (Haswell) device IDs. Note this driver only does DMA operations currently and is not plumbed for other opcodes (XOR/P+Q, CRC, etc.) But the general framework is there to add code for the other opcodes. E5 v2 and v3 device IDs are pasted below. -Jim #define PCI_DEVICE_ID_INTEL_IOAT_IVB0 0x0e20 #define PCI_DEVICE_ID_INTEL_IOAT_IVB1 0x0e21 #define PCI_DEVICE_ID_INTEL_IOAT_IVB2 0x0e22 #define PCI_DEVICE_ID_INTEL_IOAT_IVB3 0x0e23 #define PCI_DEVICE_ID_INTEL_IOAT_IVB4 0x0e24 #define PCI_DEVICE_ID_INTEL_IOAT_IVB5 0x0e25 #define PCI_DEVICE_ID_INTEL_IOAT_IVB6 0x0e26 #define PCI_DEVICE_ID_INTEL_IOAT_IVB7 0x0e27 #define PCI_DEVICE_ID_INTEL_IOAT_IVB8 0x0e2e #define PCI_DEVICE_ID_INTEL_IOAT_IVB9 0x0e2f #define PCI_DEVICE_ID_INTEL_IOAT_HSW0 0x2f20 #define PCI_DEVICE_ID_INTEL_IOAT_HSW1 0x2f21 #define PCI_DEVICE_ID_INTEL_IOAT_HSW2 0x2f22 #define PCI_DEVICE_ID_INTEL_IOAT_HSW3 0x2f23 #define PCI_DEVICE_ID_INTEL_IOAT_HSW4 0x2f24 #define PCI_DEVICE_ID_INTEL_IOAT_HSW5 0x2f25 #define PCI_DEVICE_ID_INTEL_IOAT_HSW6 0x2f26 #define PCI_DEVICE_ID_INTEL_IOAT_HSW7 0x2f27 #define PCI_DEVICE_ID_INTEL_IOAT_HSW8 0x2f2e #define PCI_DEVICE_ID_INTEL_IOAT_HSW9 0x2f2f
